Sonoma's wine scene has flourished so much in the last generation that many of the county's viticultural pioneers have become international tastemakers, producing at massive scale.

Dig a little deeper, though, and you'll find a clutch of boutique wineries whose taste and style is dictated by terroir, not by the trends guiding the bigger guys.

At Sonoma's small, often family-run wineries, a few dedicated folks see the process through from start to finish.

"We all have a hand in our product from soup to nuts," says Alice Warnecke Sutro, the 33-year-old founder of Sutro Wines in the Alexander Valley who is bringing a youthful approach to an age-old business.

Like Sutro, many among this new generation of craft winemakers like to be involved in the process as early on as the farming, before nurturing their wines through production and harvest, and ultimately to marketing and sales. The result is small batches of bright, bold, and deeply loved wines.

As warmer months approach, Sonoma's artisan winemakers are rolling out their most refreshing, thirst-quenching wines. Get a taste or a bottle at these Sonoma craft wineries.

Scribe Winery's 2016 Skin Fermented Chardonnay

Like many of Sonoma's artisan wineries, Scribe Winery is a family affair with a long history: Brothers Andrew and Adam Mariani are fourth-generation farmers and winemakers who have been producing small-batch wines since 2007. The brothers' skin-fermented chardonnay began as an experiment with a traditional winemaking process and some uncooperative grapes. After 101 days fermenting in their skins, the original batch resulted in a delicately balanced golden-hued wine with floral and tropical fruity notes; an experimental success that has become part of Scribe's annual portfolio. Taste the 2016 Skin Fermented Chardonnay ($38) at the winery (advanced reservations required) or order some from their online store. // 2100 Denmark St (Sonoma), scribewinery.com

Sutro Wines' 2017 Sauvignon Blanc

Although Alice Warnecke Sutro's family has been growing grapes at their property, Warnecke Ranch, since the 1970s, she and her husband Eliot Sutro were the first to try their hand at estate-grown wines. Under the label Sutro Wines, the couple began in 2012 with cabernet and merlot crafted from Alexander Valley's rich alluvial soils, hitting double gold right out of the gate with their 2013 Cabernet Sauvignon. This spring, Sutro Wines is releasing its first warm-weather white wine: a 2017 Sauvignon Blanc ($28) with notes of passionfruit and grapefruit peel with fennel undertones. With just 28 cases made this year, get a sip at Sutro Wines' tasting and vineyard tour (advanced reservations required) or order a bottle from their online store (shipping in April). // 13301 Chalk Hill Rd (Healdsburg), sutrowine.com

Here he specializes in Montepulciano; the upcoming 2016 vintage (due out this spring) is a fruity, black cherry and currant-flavored red juicy enough for warm weather sipping.

Belden Barns' Blanc de Noirs Sparkling Wine

The crew at Belden Barns' travelled a rough road to be able to produce quality estate-grown wines. The historic vineyard, acquired in 2005, had to be painstakingly coaxed back into production after being ravaged by virus. Today, the lovingly restored fruits of their labor are at the center of not only Belden Barns' wines, but they show up in the wines of half a dozen other makers in the region. Celebrate the coming fairer months with Belden Barns' sparkling Blanc de Noirs ($38), a dry, medium-bodied brut with notes of citrus and dark cherry. Belden is in the process of developing a tasting room so, for now, grab a bottle from their online store or at a number of SF restaurants and retailers including Lazy Bear, Foreign Cinema and Bi-Rite. // 5561 Sonoma Mountain Rd (Santa Rosa), beldenbarns.com

Preston Kalogiros' 2016 Viognier & Sauvignon Blanc

The creativity of many artisan winemakers in Sonoma goes beyond wine to artistic expression in paint, sculpture, and wood. A collaboration between two visual artists, the craft label Preston Kalogiros exemplifies the kind of curiosity and imagination they bring to their art, wrought in grapes and fermentation. This spring, Preston Kalogiros' just-released 2016 Viognier & Sauvignon Blanc ($26), with its light honey color and nose of Meyer lemon, sweet red pepper and yellow apple, is a tiny batch (just eight cases) of drinkable high art.

Carpenter Wines' 2015 Semillon

Growing up in Wine Country, young Jake Hawkes attempted to make his first chardonnay before he'd even graduated high school. These days, Hawkes and his wife, Laura Carpenter Hawkes, are crafting small batches of estate-grown chardonnay and semillon whose vines date back to the 1970s. As they describe it, Carpenter Wines' 2015 Semillon ($30) has "a ton of tang and citrus rind...and the finish is like sucking on a river stone"—the perfect makings of a summer white.
